Failing on Fremera

Meghan • PCOS Warrior, blessed with a beautiful baby girl 4-18-17 via IUI and another beautiful baby girl 6-20-19 via IUI💕
This was my second round with Fremera. First round was 2.5 mg, this past one was 5 mg. I went for an FUS ultrasound today. My follicles have stalled and we did not trigger today. My doctor upped my dosage and I began 7.5 mg today and we will do another ultrasound on Thursday with a potential trigger that day should the follicles show growth.
Anyone else have an experience like this? I'm feeling frustrated!
